Frame transmitting apparatus and method thereof

A frame transmitting apparatus transmits a frame to a frame receiving apparatus. The frame transmitting apparatus includes a accumulated-capacity-value storage unit that has stored therein an accumulated capacity value calculated; a cycle and capacity storage unit that has stored therein a cycle and a frame read capacity at every cycle; an adding unit that adds the value indicative of the capacity of the frame to the accumulated capacity value; a subtracting unit that subtracts the value indicative of the frame read capacity from the accumulated capacity value; and a transmission controlling unit that controls frame transmission by using the accumulated capacity value.
